PROPELLING MECHANISM FOR BOATS.

,SPEOIFIOATION forming part of Letters Patent No. 720,534, dated February 10, 1903.

Original application filed $eptember 2, 1902, Serial No. 121,915. Divided and this application filed November 19, 1902. $erial No. 132,007. (No model.)

To all whom it may concern.-

Be it known that I, DOWNES ELLAND NOR- 'l0N,a subject of the King of Great Britain and Ireland, residing at Hampton Hill, Middlesex county, England, have invented certain new and useful Improvements in Prop'elling Mechanism for Boats; and I dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

This application is a division of the application filed by me on September 2, 1902, Serial No. 121,915.

This invention relates to propelling mechanism for boats; and it consistsin the novel construction and combination of the parts hereinafter fully described and claimed.

In the drawings, Figure l is a plan view of the stern of a boat provided with driving mechanism according to this invention. Fig. 2 is a side view of the driving mechanism. Fig. 3 is an end View of the same.

A is the stern portion of a boat, and B is its rudder, pivoted to the stern in anyapproved manner.

0 is a propeller secured on a shaft 0, which is journaled in bearings h at the lower part of the rudder. The rudder is provided with a projection d at its rear, which-has sharp edges d adjacent to the blades of the'propeller, so that weeds may be out if they tend to wind about the propeller-shaft. The upper part of the rudder consists of an open frame B, in which a driving-shaft D is journaled.

E is a sprocket-wheel secured on the shaft D, and e is a sprocket-pinion secured on the propeller-shaft c. A drive chain 0 passes over the wheel E and pinion e and affords a means for revolving the propeller.

F is a combined spring-pulley and drivingclutch mounted on the driving-shaft D. This device F is of any approved construction and is preferably the same as shown in detail in the said application filed September 2, 1902. A flexible driving connection f is connected to the said spring-pulley and passes over guide-pulleys 3 and 4 on the frame B. Two flexible driving connections f form a continuation of the flexible connection f and pass over guide-pulleys 5, carried by the sides of the boat.

G is a handle secured to the free ends of the flexible connections f.

A double combined spring-pulley and driv-' ing-clutch H is secured on the shaft D and is constructed substantially the same as the device F. Two flexible driving connections 71. are connected to the device H and pass over guide-pulleys 7, carried by a steering cross-bar J, which is secured to the top of the rudder-frame above its pivots. These flexible connections It also pass over guidepulleys 8, carried by the sides of the boat, and their free ends are connectedto a handle h. The operators sit on the boat-seats 7c and pull upon the handles alternately. One of the operators can also steer the boat by placing the handle h in an oblique position, so as to pull upon one of the flexibleconnections and release the other, thereby turning the rudder on its pivots.

What I claim is i The combination, with a boat, a rudder pivoted thereto, and a steering cross-bar carried by the said rudder; of a propeller journaled in bearings on the said rudder, a driving-shaft also journaled in bearings on the said rudder, driving mechanism operatively connecting the said driving-shaft and propeller, two combinedspring-pulleys and driving-clutches mounted on the said driving-shaft, guide-sheaves carried by the end portions of the said cross-bar, and flexible driving connections for revolving the said pulleys and also operating to steer the boat, substantially as set forth.

In testimony whereof I affix my signature in presence of two witnesses.
